In advance of the Thanksgiving Holiday Travel period, the TSA has open a third Pre-Check security lane at BWI-Marshall Airport.

The special lanes will be available at Concourses A, C and D.

Eight airlines including Southwest, Alaska, American, Delta, Hawaiian, United Airlines, US Airways and Virgin America are participating in the program.

Under the program, passengers don't have to remove their shoes, belts or coats to get through security.

Laptops also don't have to be removed from their bags. Liquids in carry-on bags won't have to be screened separately.

The program is open to frequent fliers who opt-in through airlines, members of the military and people who are in the U.S. Customs and Border Protection, and members of the military.

Passengers can also be selected by the airlines.

TSA officials say passengers who have bought tickets online in recent months will note a special mark in the upper left hand corner of their boarding pass to see if they are eligible to go through pre-check.

Officials do say, even in the pre-check lanes, passengers that don't clear security will face an additional search.

The program is in place at more than 100 airports across the country.

The program has been in place at BWI-Marshall for about a year.

It's being expanded after Southwest Airlines, the largest carrier at the airport, joined the program.

Just this week, BWI-Marshall was ranked 19th on Travel & Leisure magazine's list of the 20-best airport security checkpoints in the country.
